Peanut Butter Cup Cupcake Ingredients
For the Cupcakes
• All-Purpose Flour – Forms the backbone of these cupcakes; you can swap it for gluten-free flour if needed.
• Dutch Process Cocoa Powder – Provides deep chocolate flavor; unsweetened cocoa is a suitable substitute.
• Baking Powder & Baking Soda – Essential leavening agents; be sure they’re fresh for a perfect rise.
• Salt – Enhances sweetness and balance; using kosher salt will elevate your baking.
• Unsalted Butter – Adds richness and moisture; coconut oil can be a great dairy-free alternative.
• Granulated White Sugar – Sweetens and keeps the cupcakes moist; try brown sugar for a hint of caramel flavor.
• Egg & Egg Yolk – Ensures moistness and acts as a binder; flaxseed meal works as an egg substitute if desired.
• Vanilla Extract – Brightens the overall flavor; always opt for pure vanilla for the best taste.
• Sour Cream – Adds a lovely softness; yogurt can easily replace it too.
• Whole Milk – Contributes to moistness; any non-dairy milk can replace it without losing flavor.
For the Ganache
• Peanut Butter Chips – This is the star ingredient for a rich ganache; feel free to use chocolate chips for a different twist.
• Heavy Cream – Essential for that creamy ganache texture; you can substitute it with full-fat coconut milk for a dairy-free version.
For the Frosting
• Cream Cheese – Creates a luscious base for the frosting; vegan cream cheese is a perfect dairy-free alternative.
• Powdered Sugar – Gives sweetness and helps in stabilizing the frosting; there’s no good substitute here.
• Creamy Peanut Butter – Adds the ultimate peanut flavor to your frosting; regular peanut butter yields the best texture.
These Peanut Butter Cup Cupcakes are sure to impress, bringing joy to every bite!
Step‑by‑Step Instructions for Peanut Butter Cup Cupcakes
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) and line a cupcake pan with 12 liners. Ensure the liners are placed firmly in each cup to hold your delightful batter. Gather your mixing bowls and measuring cups, setting yourself up for a smooth baking experience.
Step 2: Mix Dry Ingredients
In a small bowl, whisk together the all-purpose flour, Dutch process cocoa powder, baking powder, baking soda, and salt. This step aerates the dry ingredients, promoting a light and fluffy texture in your Peanut Butter Cup Cupcakes. Set aside your bowl while you move on to the wet ingredients.
Step 3: Cream Butter and Sugar
In a large bowl, cream the unsalted butter and granulated white sugar together using an electric mixer on medium speed for about 2-3 minutes until light and fluffy. The mixture should lighten in color and become creamy, indicating it’s well combined. Then, add in the eggs and vanilla extract, mixing until the batter is pale and smooth.
Step 4: Add Wet Ingredients
Stir in the sour cream and whole milk until fully incorporated into your butter-sugar mixture. This addition will make your cupcakes rich and moist. Pay attention to achieving a smooth consistency; any lumps should be mixed out before proceeding to the next step.
Step 5: Combine Dry and Wet Ingredients
Gradually fold in the dry ingredient mixture into your wet mixture. Do this gently until just combined; overmixing can lead to dense cupcakes. The batter should be thick and glossy, ready to be divided evenly into the cupcake liners for the ultimate Peanut Butter Cup Cupcakes.
Step 6: Bake and Cool
Scoop the batter into the liners, filling them about two-thirds full. Bake in the preheated oven for 17-20 minutes, or until a toothpick inserted into the center comes out clean. Once done, let them cool in the pan for about 10 minutes before transferring to a wire rack to cool completely.
Step 7: Prepare the Ganache
Heat the heavy cream in a small saucepan over medium heat until it begins to steam; do not let it boil. Pour this hot cream over the peanut butter chips in a separate bowl, stirring until completely smooth. Allow the ganache to cool at room temperature until it thickens enough to pipe.
Step 8: Make the Frosting
In a clean mixing bowl, whip the unsalted butter until fluffy, about 3-5 minutes. Gradually add cream cheese, mixing until combined, then continue to add the powdered sugar slowly followed by the creamy peanut butter, mixing until it reaches a light and airy consistency suitable for frosting your cupcakes.
Step 9: Fill and Frost the Cupcakes
Core the center of each cooled cupcake with a small knife or a cupcake corer. Fill each cavity with your luscious ganache using a piping bag or a spoon. Finally, pipe the creamy peanut butter frosting generously on top, creating swirls for an appealing look, and garnish each cupcake with mini Reese’s cups for a delightful finish.

How to Store and Freeze Peanut Butter Cup Cupcakes
Room Temperature: Enjoy your cupcakes fresh for up to 2 days stored in an airtight container at room temperature. This keeps their texture soft and delicious.
Fridge: For extended freshness, store the cupcakes in an airtight container in the fridge for up to 5 days. Allow them to come to room temperature before serving for the best taste.
Freezer: To freeze, wrap each cupcake individually in plastic wrap, then place in a freezer-safe bag. They can be frozen for up to 3 months. Thaw at room temperature before enjoying.
Reheating: If you prefer warm cupcakes, simply microwave them for 10-15 seconds. Enjoy the delightful combination of flavors in your Peanut Butter Cup Cupcakes!
Make Ahead Options
These Peanut Butter Cup Cupcakes are perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare the cupcake batter and store it in the refrigerator up to 24 hours in advance; this helps achieve a fresher taste. Additionally, the ganache can be made ahead and refrigerated for up to 3 days—just let it come to room temperature before filling the cupcakes. For the frosting, you can whip it up ahead of time and store it in the fridge for up to 2 days; rewhip briefly before piping to restore its fluffiness. When you’re ready to serve, simply fill the cooled cupcakes with ganache and pipe on the frosting for fresh, delicious results, making your baking experience easier and more enjoyable!

Tips for the Best Peanut Butter Cup Cupcakes
- Room Temperature Ingredients: Ensure your butter and eggs are at room temperature; this helps achieve a light and fluffy cupcake texture.
- Avoid Overmixing: Mixing the batter just until combined will prevent dense cupcakes. Too much mixing activates the gluten in the flour.
- Use an Ice Cream Scoop: For even distribution of batter into the liners, use an ice cream scoop. This ensures consistent cupcake sizes and even baking.
- Check for Doneness: Insert a toothpick into the center of the cupcakes to check if they are done. It should come out clean to avoid underbaking.
- Cool Ganache: Allow the ganache to cool to the right consistency before filling the cupcakes; it should thicken enough to hold its shape but still be smooth.
- Chill Your Frosting: If your frosting becomes too warm during mixing, refrigerate it briefly before whipping again. This helps restore its fluffy consistency.

Peanut Butter Cup Cupcakes Recipe FAQs
How do I choose ripe ingredients for these cupcakes?
For the best results, ensure your butter and eggs are at room temperature before starting. This helps create a light and fluffy texture. When selecting peanut butter, opt for creamy, regular peanut butter instead of natural varieties, as they tend to separate and may affect the frosting’s consistency.
What’s the best way to store leftover cupcakes?
Store your Peanut Butter Cup Cupcakes in an airtight container at room temperature for up to 2 days. For longer freshness, refrigerate them for up to 5 days, but remember to allow them to come to room temperature before serving to maintain their delicious taste and texture.
Can I freeze these cupcakes, and if so, how?
Absolutely! To freeze your Peanut Butter Cup Cupcakes, individually wrap each one in plastic wrap and place them in a freezer-safe bag. They can be frozen for up to 3 months. When you’re ready to enjoy, simply thaw them at room temperature. If you’d like them warm, pop them in the microwave for 10-15 seconds!
What should I do if my cupcakes turn out dense?
If your cupcakes come out dense, it could be due to overmixing the batter or not measuring the flour correctly. Always mix until just combined and use a spoon to lightly spoon flour into your measuring cup without packing it down. This helps retain that lovely light texture we all adore in cupcakes!
Are there any dietary considerations for pets or allergies?
These cupcakes contain common allergens such as gluten, dairy, and peanuts. It’s best to keep them away from pets, especially dogs, as chocolate and certain sweeteners can be toxic to them. If you’re baking for someone with allergies, consider making substitutions like gluten-free flour, dairy-free butter, and using egg replacements like flaxseed meal.
